Recently bought an 07 GT M5 vert with JLT, UDP, LT, catless x-pipe, and 3.73's. With a canned Bama tune it's pretty strong above 4500 rpm to the 6400 limit, but response in 3-4-5 gears is less than desirable. The car replaces a series of motorcycles going back 50 years; all my M/C's in this century have been capable of 10-12 seconds in the quarter, so I'm looking to tune up to at least 12-second power. Realistically, that means some form of forced induction and a custom tune.
The car will be used for 5-10k mile tours, so longevity, ease of service, and good control of underhood temps are the priorities. Ability to retain the headers, UDP's, and "x" for additional power would also be a plus, as would decent fuel economy for cruising on America's highways and byways.
From all I've been reading, it appears that a centrifugal s/c sharing crankcase oil would be the most efficient, coolest, and least intrusive setup. It could also use the stock TB and intake and, with its own separate pulley, could [I suppose] retain the UDP's. OTOH some of the PD blowers like Edelbrock claim minimal parasitic losses, and they just look better. Turbos look way too complex for my skillset.
Haven't found much info about the relative merits of the different FI types for my priorities, so all considered opinions are gratefully welcomed. If I'm wrong, just say so - and why.
